Not a MkIII, but the same Jag 5.0. 2010 LR4 I picked up for a buddy of mine, $4500!
It's "noisy" up front, so will just go ahead and do the full set. It had supposedly had them all done in '15 (same owners since '11), but I'm guessing they used the plastic pins still, instead of aluminum. Cost them $5500.....ouch, lot of coin for it to sound like a diesel....
I was going to check the chain, then maybe just do the guides etc, but can't find an accurate way to check it!
Would save a load of time, plus all the specialist tools.
No CEL on, runs great, just noisy. Hooked up the GAP tool from the wife's '11SC, and no untoward readings.
Thoughts on the guides? Any way to tell you're getting the new style guides etc?
Will try to take pics and give any hints. Lots of threads, but few "complete" ones.
